Show HN: Mcptoon – MCP CLI client that cuts tool discovery tokens by 97%

Mcptoon is a CLI client that dramatically reduces token consumption when using MCP (Model Context Protocol) servers by converting JSON output to a compressed format called TOON (Token-Optimized Object Notation). The tool achieves 97% token savings on tool discovery and 56% on structured data results while maintaining zero dependencies and working across all major platforms and AI agents. It can be easily installed via pip and connects to any MCP server using stdio or HTTP protocols.
